D. Both the public interface name and the private interface name can vary on different nodes.

Correct Answer: C
Explanation/Reference:
Checking Network Requirements
Each node must have at least two network interface cards (NICs).
Interface names must be the same on all nodes.
Public NIC must support TCP/IP and Private NIC UDP.
Public IP must be registered in the domain name server (DNS) or the /etc/hosts file.
# cat /etc/hosts
##### Public Interfaces – eth0 (odd numbers)####
xxx.xxx.100.11
host01.example.com host01
xxx.xxx.100.13
host02.example.com host02
IF GNS is used, the Cluster GNS address must be registered in the DNS.
Prevent public network failures when using NAS devices or NFS mounts by starting the Name Service Cache Daemon.
# /sbin/service nscd start
